SUMMARY: Routing outside a new NIS+ domain

I reported a problem involving a new NIS+ domain. (Full description
below.) We were having problems routing to other machine outside the
domain.

I received a number of suggestions to the effect that it didn't sound
as though NIS+ was the problem.

These suggestions were in fact correct. Due to another problem we had
turned off IP forwarding on our intended gateways.
